Quite awhile ago, I seperated the carburetor/intake manifold from the engine in my '87 Wrangler 4.2L. Anyways, I'm looking at the intake manifold now and there's a red wire coming out of the bottom of it with a white plug on the end. It's right below the EGR valve. Does anyone know what this is/where it goes?

It wouldn't be EGR related, the only thing going to the EGR valve would be a vacuum line. If it's single wire it could be from a knock sensor possibly? I'm not really sure._________________06 Rubicon

The wire isn't that long, so I'm thinking it connects to the carburetor somewhere. I've got a new carb minus the stepper motor as I ripped out the computer and am getting rid of all traces of emission control.

I'll probably just remove the wire and what it's attached to and make a plate to cover the hole just like where the EGR valve went...

Do you have anything hooked to the new electric choke? If not, that could be the wire. I'm not quite sure how it works, it will probably apply voltage to the choke when you first start up. But I'm not sure, everything I have that is carbureted has mechanical choke, with the bi-metal spring inside. So maybe someone with more knowledge on this could chime in._________________06 Rubicon

I haven't got that far yet. I'm in the process of cleaning up the intake and designing a cover plate to replace the EGR Valve. I was going to remove the plate that this red wire connects to, but I'm not sure if I should.
